1-Check the internet connection
When this happens, the first thing to do is to check if the tablet has a working internet connection. The device needs an active internet connection to receive changes from the web. After you publish you can continue using your menu offline.

-Tap the Finedine logo at the bottom right 3 times.
-Select "Settings" from the list.
-Log in with your credentials.
